Coral reefs face a large variety of challenges. From climate change, to overfishing and local pollution, coral reefs are under threat. Uhu (parrotfishes) in Hawai‘i play a crucial role as guardians of the corals. Uhu eat the seaweeds that often cover and smother corals and consequently provide more space for corals to grow and thrive. Unfortunately, uhu are severely overfished in Hawai‘i and their ability to protect corals is currently compromised.
